19x8 front

The car is a 69 Camaro, that has been minitubbed with DSE tubs and running a Speedtech torque arm rear and their road assault package in the front. The car is going to have a nice low stance. So as the title says, what do you guys think, 345/25/20's or 335/30/20's?! I'm worried that the 345's are a little to rubber bandish, and the 335's are a little to tall and I won't be able to get the right ride height! The front tire will be a 245/35/19 (Full front subframe for a wider tire wasn't in the budget unfortunately).

Obviously, pics go a long way ! I did a search but didn't find to many running the above combo's!

By the way, wheels are the brand new Hot Rods by Boyd 2 piece billet HR99's with Charcoal center and polished lip. I dealt with Chris Coddington and the customer service was nothing short of incredible, and the wheels should be here in 3 to 4 weeks. I will be sure to post up pictures when they arrive!

245/35/19 = 25.75"OD (3.4" sidewall)

335/30/20 = 27.9"OD (4" sidewall)

345/25/20 = 26.8"OD (3.4" sidewall

As you can see above if you base it on your front tire size you have 3.4" sidewall and approx 25.75" overall height. With the 1" diameter larger rear tire you want to carry at a MINIMUM the same sidewall (relating to 1" taller rear tire).

The 345/25/20 matches the front tire perfectly!

However it depends on the look you want to go for. An approx 28" rear tire is pretty sall, so will give the car the "stuffed" look. It's over an inch taller than the other rear tire option and 2 inches taller than the front! Again depends on the look you're going for.

If it were me, I'd go the 345/25/20. You get the additional width (just less than 1/2" wider) which is always a good thing and it matches the front perfectly.

I'm going with 18/19 combo on mine, but for reference you can see us test fitting a 345/25/20 on my car so you can get an idea of the aspect ratio (sidewall).

Good luck!
